The Study on Strength Properties by Cluing Temperature of High Volume Fly-Ash Concrete

플라이애쉬를 다량 치환한 콘크리트의 양생온도에 따른 강도특성에 관한 연구

In this study, a high volume fly-ash substituted concrete experiments in two curing temperature circumstances - 35${\circ}$, 20.${\circ}$, High volume fly-ash concrete is tested in fresh concrete properties and hardeded concrete properties. There is slump, air contents, concrete setting tests. 3, 7, As fresh concrete test items and 28 days water curing compressive strength is measured in the hardened concrete test. The purpose of this study is to submit a various fly-ash concrete data for application to field. The result of this study is that the best strength is developed at the plain concrete cured 20 ${\circ}$, and Mixing F43 shows the best strength among specimens which cured at 35${\circ}$,
